Fosteris a programmer and writer who has spent the past nine years creating desktop appli- cations, database front ends, Web sites, communications software, technical documentation, and hand- held applications. He has been developing Palm OS applications almost as long as the platform has existed, starting with his first Pilot 5000 and progressing to more complicated wireless software for Symbol’s 1700 series. Lonnon fills his sparse free time with tactical tabletop gaming, recreational Perl coding, and reading everything he can get his hands on. Glenn Bachmannis a noted author of several books and articles on Palm OS programming and mobile computing. Glenn is also president and founder of Bachmann Software, a leading provider of wireless file management, networking, backup, and printing software products for Palm OS, Pocket PC, and Symbian handheld computing platforms. Founded in 1994, Bachmann Software (www.bachmannsoft- ware.com) has established itself as a leading contributor to the mobile and wireless economy through its utility software products and partnerships with many of the key companies in the mobile computing arena. Bachmann’s PrintBoy, FilePoint, Mobile Backup, and Mobile Utilities are among the best-selling software utilities for handhelds and smartphones. First and foremost I thank my acquisitions editor, Chris Webb, for remembering me from our previous collaborations and providing me with the opportunity to participate in writing this book. I also thank my development editor, Eileen Bien Calabro, who bore the difficult task of keeping the book on track with just the right amount of poking and prodding to the author. I also thank Lonnon Foster for creating the phenomenally successful Palm OS Programming Bible, the second edition of which is the predecessor and foundation of this book. Through Lonnon’s clear and concise writing style and attention to detail, he has helped programmers around the world become Palm OS programmers. There are so many people in the Palm OS developer community—at PalmSource, palmOne, and other software companies—who continue to be the heroes of our little mobile computing industry. These fine folks are responsible for the fantastic handhelds, smartphones, operating systems, and software applica- tions that make it such a delight to participate in and contribute to the success of the Palm Economy. My hat goes off to you all. Thanks are also due to the team at Bachmann Software, truly the finest and most dedicated people I have ever worked with. Finally, I thank my wife for supporting me in my never-ending adventures in growing a software com- pany. I also thank my three wonderful children, who seem to have grown up under the impression that it is entirely normal for their father to possess 58 different handhelds.
